Construction method of fabricated double-wall steel cofferdam universal for weir plate and trestle panel
According to the construction method of the assembly type double-wall steel cofferdam universal for the weir plate and the trestle face plate, the assembly type double-wall steel cofferdam comprises a double-wall steel cofferdam welding layer and a double-wall steel cofferdam assembly layer, and the double-wall steel cofferdam welding layer is formed by splicing, welding and enclosing four corner modules and a plurality of plane modules; the bottom of the double-wall steel cofferdam assembly layer is in mortise and tenon joint connection with the top of the double-wall steel cofferdam welding layer; the double-wall steel cofferdam assembly layer is divided into a plurality of sections connected in a mortise and tenon mode in the vertical direction, and each section is formed by annularly splicing four corner assembly modules and a plurality of plane assembly modules in a mortise and tenon mode. A transverse anchoring tensioning system used for transverse tensioning and a vertical anchoring tensioning system used for vertical tensioning are arranged in the coaming bin of each corner assembly module and the coaming bin of each plane assembly module. According to the construction method, the double-wall steel cofferdam structure is assembled and installed in a tensioning bundle and mortise and tenon joint splicing mode, underwater cutting operation is not needed, the working efficiency and safety are improved, and the double-wall steel cofferdam structure can be quickly disassembled and converted into building parts of a steel trestle.
一种堰板与栈桥面板通用的装配式双壁钢围堰的施工方法，该装配式双壁钢围堰包括双壁钢围堰焊接层和双壁钢围堰装配层，双壁钢围堰焊接层由四个转角模块和多个平面模块拼焊圈围而成，双壁钢围堰装配层的底部与双壁钢围堰焊接层的顶部榫卯接高连接；双壁钢围堰装配层在竖直方向分为多个采用榫卯连接的节段，每个节段都由四个转角装配模块和多个平面装配模块榫卯环形拼接组成，每个转角装配模块和平面装配模块的围板仓内都设置有用于横向张紧的横向锚拉张紧系统和用于竖向张紧的竖向锚拉张紧系统。本施工方法将双壁钢围堰结构采用张紧束和榫卯拼接的装配式安装，不需要进行水下切割作业，提高工作效率和安全性，可快速拆装转换为钢栈桥的搭建零部件。
